Photometric determination of crater's depth on Enceladus
Abstract
We show here that it is possible to overcome the difficulty at determining the crater's depth of planetary bodies without radar or laser altimetry, by the use of the multi-angle geometry of imaging data. We present here for Enceladus the adaptation of a macroscopic surface roughness model, developed by [4] and well documented by [1,2]. This model allows reproducing the average photometric behavior of a crater and constraining its aspect ratio with a very good accuracy.
